Giới thiệu Bảng Mạch Sạc Pin Lithium 3s 20a 18650 Pcb Bms 12.6v Cell 59x20 X 3.4mm

Note : more than 3A current discharge products rate is more than 3C Ratio calculation formula : 1C rate of the battery , 2000 capacity is equal to 2AH 1 2A maximum working current . 3C ratio battery , 2000 capacity is equal to 2AH * 3 = 6A maximum working current . In use battery heats is ratio is not applicable to , this kind of situatic can't use for a long time , the battery will soon be damaged
Note 1 : in accordance with the diagram wiring 0 V , 3 . 7V ( b- ) ( B1 ) ( B2 ) , 11 . 1 V , 7.4 V ( B + ) don't deliberately short circuit

Note 2 : after connected line need to recharge , just can have output
Note 3 : 3 series battery , please make sure that each set of battery voltage , if not , please separate with each set of batteries in series . Discharge test , the battery voltage drops quickly is a bad battery .
Note : don't put the good cells and in bad ! Three groups of battery capacity / internal resistance as close as possible ! ( 2 + 1 good battery , the use effect of poor battery = the use effect of three bad battery )
